Description/Explanation: Please see attached. P-1(B) Page 1 of 1 Revised 07/10 c Project Description The existing HPLS has several operational and design issues and is in need of replacement to meet capacity needs, meet current code requirements, enhance the structural integrity, and decrease the amount of maintenance required. Main design issues include the following: • Sand & Rags: The New lift Station will need to provide for a means to easily collect and dispose of collected sand. Sand accumulation can be in excess of several feet per month. The new HPLS will need either a new arrangement or a comminutor or other method to prevent rags fi'om clogging the pumps. • Grease: The new lift station will need to provide the means of controlling the amount of grease entering into the wet well. The City has currently adopted a Fats, Oils and Grease (FOG) ordinance, which should reduce the amoimt of FOG discharged into the wastewater system of the food establishments, but historical grease accumulation is very significant at the lift station. • Holding Capacity: The lift station is adjacent to public beaches. It is desired that the new HPLS have a four hour holding capacity to meet build-out conditions in accordance with the City's 2003 Wastewater Master Plan. • Odor & Ventilation: The existing lift station has significant odor from the wastewater that needs to be controlled. In addition the ventilation system for maintenance staff needs to meet current code requirements. The new lift station will have a ventilation system that effectively controls odor issues and hazardous gases. • Electrical: The new lift station will have the motor control center and other electrical panels located above the grade to comply with current electrical codes. The design shall consider programmable controllers that can be accessed remotely through SCADA system and laptop computers maintained by on call staff. • Structural: There is concrete spalling and corrosion of the reinforcing steel in the existing wet well. The structural design of the new lift station shall include a PVC liner for the wet well. • Site Security: The new lift station will have a Closed Circuit Camera (CCTV) security system for site security and other measures to meet security requirements. Safe access to and from the site off Carlsbad Boulevard shall be included. It is anticipated that the existing standby power generator and the building enclosing the generator can be maintained for use and design ofthe new lift station. to IT Cl • • • CO m a HI C3 U.S. Postal Servi ^RTIFIED MAILrM RECEIPT (H^esf/c Mail Only; No Insurance Coverage Providif^ for delivery information visit our website at www.usps.com:.

The application documents submitted for this project are complete. However, staff has identified several issues of concern. Prior to next submittal, it is suggested the following items are adequately addressed. Additional items of concern maybe identified upon review next submittal: Issues of concern: On page 7 of the preliminary SWMP, it is indicated that this project is exempt from hydromodification because it discharges directly into an exempt system that discharges directly to the Buena Vista Lagoon. However, according to expanded HMP exemption criteria of Figure 2-1, Node 5 on page 32 of City SUSMP, the exempt receiving waters are San Diego Bay, Pacific Ocean and exempt river reaches listed in Table 2-4 on page 34 of City SUSMP (please see attached). Buena Vista Lagoon is not on the list of exempt receiving waters. The expanded HMP exemption of Figure 2-1, Node 6, provides potential exemptions for projects discharging directly to a tidally-influenced lagoon. (Potential exemption requires analysis to assess the effects of freshwater/saltwater balance on the lagoon system biology). This project discharges into Buena Vista Lagoon. However, Buena Vista Lagoon is not a tidally-influenced lagoon therefore this project is not exempt from hydromodification requirements. The proposed bio-retention system shown on the preliminary grading plan can be designed as a treatment control BMP and a flow control BMP to comply with hydromodification requirements using an integrated approach provided in the City SUSMP. A San Diego BMP sizing calculator for hydromodification and LID facilities by Brown and Caldwell is now available. Go to http://www.proiectcleanwater.org and click on the BMP sizing calculator.

Please revise the cross- section to include a minimum ponded depth of 4" to allow infiltration plus 2" minimum freeboard. Include a minimum of 18" thick of engineered soil layer for treatment control purposes and a gravel layer for storage for flow control purposes to comply with hydromodification requirement. Use 30% void within the gravel layer for storage volume. Provide a longitudinal cross-section ofthe bioswale showing the details ofthe proposed check dams. Ensure that the check dams provide a 4" minimum required ponded depth. • The impervious area does not appear to drain into the proposed bioretention swale as indicated by the proposed contours shown on the grading plan sheet C-5. Please revise finish grade to allow run-off to drain into the upper portion of the proposed bio- retention swale to maximize treatment. • Provide soils update letter from the soils engineer that addresses the suitability of the proposed bio-retention swale and provide design recommendations forthe said facility. Previous comment: A portion of the new force main pipeline crosses private property. Please obtain sewer easement and show proposed sewer easement on the site plan.

The lift station project site consists of two city-owned parcels and contains an existing lift station and disturbed area. The force main addition follows a new alignment under Carlsbad Boulevard and along Laguna Drive before connecting with the existing force main at Jefferson Street. The proposed project includes the replacement of the existing Home Plant sewer lift station and force main which have reached their useful life. The new station will be located adjacent to the existing station and will have a generally equivalent capacity. The new force main will have a different alignment than the existing force main. The existing force main will not be abandoned, but will remain available as a back-up to the new pipeline to provide redundancy in order to reduce risk of wastewater spiN. The force main will be constructed by directional digging, as well as open trench. No sensitive habitat will be disturbed bythe project. In response to your application, the Planning Department has prepared this comment letter. Please note that the purpose of an Early Assessment is to provide you with direction and comments on the overall concept of your project. This Earlv Assessment does not represent an in-depth analvsis of vour proiect. It is intended to give vou feedback on critical issues based upon the information provided in vour submittal. This review is based upon the plans, policies, and standards in effect as of the date of this review. Please be aware that at the time of a formal application submittal, new plans, policies, and standards mav be in effect and additional issues of concern mav be raised through a more specific and detailed review.

The project is located in the coastal zone. Village and Mello II Segments, and a different Coastal Development Permit (CDP) will be required per Carlsbad Municipal Code (CMC) Section 21.201.030 for the portion of project in each segment. Please submit two CDP applications for development proposed in and out of the Village Review Area. Two CDP's are necessary because the project is subject to the approval of the Planning Commission outside of the Village Review Area and the approval of the City Council inside the Village Review Area. 3. The proposed work in the Village Area is subject to a Major Village Review Permit per CMC Section 21.35.070. Please submit a Major Village Review Permit application. , , 4. The proposed lift station is subject to a Conditional Use Permit (CUP) within the OS and R-A zones. Please submit a CUP application. 5. The project is exempt from the California Environmental Quality Act (CEQA) pursuant to State CEQA Guidelines Section 15303 - New Construction or Conversion of Small Structures. The proposed project mostly contains below grade vaults and structures. A new 260 square foot control building will be constructed above grade. The total proposed square footage of all seven structures is approximately 2,000 square feet. Therefore, it is concluded that the project is considered new construction of small structures. In addition, Section 15303(d) specifically exempts sewer extensions such as the proposed force main. 6. Overall, the project will need to be approved by the Planning Commission and City Council. 7. The following notes shall be placed on the plans: • Construction staging is not permitted in environmentally sensitive areas. Staging areas shall be subject to City Engineer approval. • Migratory Bird Treaty Act Compliance Prior to removal or damage of any active nests or any tree pruning or removal operations during the prime nesting season, that being from March 15 to May 30, a qualified biologist shall survey the trees to determine if there are any active nests within 500 feet of the area of tree removal or pruning. If any active nests are located within 500 feet, no tree pruning or removal operations can occur until the nests are vacated or until the end of the prime breeding season, whichever occurs later. In addition, priorto any tree removal or pruning operations proposed outside ofthe prime nesting season but within the period of February 15 to August 31, a m and Force Main Replacement ^""^ EA 10-07 - Home Plant Lift Sraffon and Force Main Replacement October 18, 2010 Page 3 confirmation is required from a qualified biologist that no disturbance to active nests or nesting activities would occur.

Environmental review for compliance with the California Environmental Quality Act (CEQA) will need to be performed prior to construction. Based on the location of the project, adjacent to the State of California's Wildlife Reserve, Coastal Zone, environmentally sensitive habitat area (ESHA), and near a Hardline Conservation Area (Buena Vista Lagoon), as depicted in the City of Carisbad's Habitat Management Plan (HMP), dated November, 2004, the completion of an Initial Study for a Mitigated Negative Declaration (MND) is required for the project. For the reasons listed above, the project must comply with the adjacency standards listed in HMP Section F (3), which addresses development (including demolition) on sites that are adjacent to wildlife preserves. The adjacency standards are intended to prevent negative effects on wildlife preserves. The adjacency standards include the following categories: Fire Management (A), Erosion Control (B), Landscaping Restrictions (C), Fencing, Signs and Lighting (D), and Predator and Exotic Species Control (E). See pages F-16 through F-22 of the City's HMP for more information on adjacency standards. Project must also demonstrate compliance with the Additional Conservation Standards for Coastal Zone properties found on HMP pages D-114 to D-120. Please revise the plans accordingly. 2. The Project's 2009 Biological Resources Report is outdated. Please provide a new report, based on survey data no older than one year. Further, the Report needs to reflect the entire project, including the sewer pipeline, and shall be prepared consistent with the City's Guidelines for Biological Studies available online at http://wvwv.carisbadca.gov/services/ environmental/hmp/docs/Documents/guidelines/ guidelines-bio-studies 2008-09-30.pdf. If impacts to sensitive habitat are identified, a Habitat Management Plan (HMP) pemnit would be required. 3. Verify with ASM Affiliates, who prepared the Cultural Resources Study, dated October 6, 2009, that the Report is not outdated and includes the footprint of the enfire project including the sewer pipeline. 4. Depict the locafion of all major vegetafion, showing size and type, offsite of the project for a distance of 150 feet. In addifion, depict the 100 foot wetland boundary line. 5. Indicate the exisfing and proposed grades and the height on all building elevafions in relafion to Mean Sea Level (MSL). 6. Depict the dimensions and square footage of each structure on the site plan (sheet 50). 7. Include the total cubic yards of cut, fill, import, and export on Sheet 9 of the plan set. 8. Provide a color board (no larger than 9" x 12"), showing a sample of the material and color of the above grade structures. 9. Document and report on vegetafion that was apparenfiy cleared as part of the recently completed Beech Avenue sewer project. CQP 11-06/CUP 11-02/CDP 11-07/RP 11-09 - HOME PLANT LIFT STATION & FORCE MAIN REPLACEMENT May 26, 2011 Page 3 Engineering: None ISSUES OF CONCERN Planning: 10. The sewer lift stafion is located at the northern entrance to the city and is very visible to motorists, bicyclists and pedestrians as they travel on southbound Carisbad Boulevard. The proposed black ornamental steel fence that will surround the lift stafion does not provide adequate shielding of the existing and proposed lift stafion structures. Please consider a four foot high block wall with a two foot omamental fence on top as shown on the attached photo of the existing sewer lift station on El Fuerte Street. The block wall does not have to be located on the western boundary of the property as there are no view concerns from that direction. Furthermore, include additional vegetafion between the proposed eastern perimeter fence and southbound Carisbad Boulevard. Include a note on the landscape plans stafing that the exisfing landscaping will be maintained on an annual basis. 11. Provide a color rendering of the revised landscape plan. Furthermore, to provide assurances that the proposed and exisfing landscaping are adequate to screen the structures, please provide the eastern elevation depicfing the existing and proposed sewer lift station structures and landscaping. 12. Include on all sheets the application numbers in the upper right corner (CDP 11-06/ CUP 11- 02 & CDP 11-07/RP 11-09). Please resubmit the plans on full size sheets (24" x 36"). 13. Depict the footprint of the proposed sewer lift station within the boundaries of APN 155-200- 03 and 155-200-02. 14. Change "Rail Trail" to Coastal Rail Trail on all sheets. 15. Depict all staging areas, including equipment and material storage areas. Include the following wording under General Notes # 13 on Sheet #2, that all direct impacts to coastal sage scrub (including disturbed forms) shall be avoided during construction through the placement of temporary fencing and monitoring by a qualified biologist. 16. Other items required and applicable to this project are noted on the attached redline drawings. Please return the redline drawings with your next submittal. Engineering: 17. On page 7 of the preliminary SWMP, it is indicated that this project is exempt from hydromodificafion because it discharges direcfiy into an exempt system that discharges directiy to the Buena Vista Lagoon. However, according to expanded Hydromodificafion Management Plan (HMP) exempfion criteria of Figure 2-1, Node 5 on page 32 of City SUSMP, the exempt receiving waters are San Diego Bay, Pacific Ocean and exempt river reaches listed in Table 2-4 on page 34 of City SUSMP (please see attached). Buena Vista Lagoon is not on the list of exempt receiving waters. The expanded HMP exempfion of Figure 2-1, Node 6, provides potenfial exempfions for projects discharging directly to a fidally-influenced lagoon. (Potenfial exempfion requires CDP 11-06/CUP 11-02/CDH 11-07/RP 11-09 - HOME PLANT LIFT STATION & FORCE MAIN REPLACEMENT May 26, 2011 Page 4 analysis to assess the effects of freshWater/saltwater balance on the lagoon system biology). This project discharges into Buena Vista Lagoon. However, Buena Vista Lagoon is not a fidally-influenced lagoon therefore this project is not exempt from hydromodification requirements. The proposed bio-retenfion system shown on the preliminary grading plan can be designed as a treatment control BMP and a flow control BMP to comply with hydromodificafion requirements using an integrated approach provided in the City SUSMP. A San Diego BMP sizing calculator for hydromodificafion and LID facilifies by Brown and Caldwell is now available. Go to http://www.projectcleanwater.org and click on the BMP sizing calculator. 18. The bio-retenfion swale cross-secfion shown on sheet C-8 does not comply with the design criteria provided on page 85 and 86 of the City SUSMP. Please revise the cross-section to include a minimum ponded depth of 4" to allow infiltration plus 2" minimum freeboard. Include a minimum of 18" thick of engineered soil layer for treatment control purposes and a gravel layer for storage for flow control purposes to comply with hydromodification requirement. Use 30% void within the gravel layer for storage volume. 19. Provide a longitudinal cross-section of the bioswale showing the details of the proposed check dams. Ensure that the check dams provide a 4" minimum required ponded depth. 20. The impervious area does not appear to drain into the proposed bioretention swale as indicated by the proposed contours shown on the grading plan sheet C-5. Please revise finish grade to allow run-off to drain into the upper portion of the proposed bio-retenfion swale to maximize treatment. 21. Provide soils update letter from the soils engineer that addresses the suitability of the proposed bio-retenfion swale and provide design recommendations for the said facility. 22. Previous comment: A portion of the new force main pipeline crosses private property. Please obtain sewer easement and show proposed sewer easement on the site plan. 23.

The existing HPLS is located within the City ofCarlsbad on the south side ofthe Buena Vista Lagoon on Carlsbad Boulevard and adjacent to the North County Transit District's rail road track right-of-way. The existing sewer lift station includes 3 pumps (2 operating and 1 standby) with a capacity of 800 gallons per minute (gpm) each, with a total dynamic head of 70 feet. The lift station is a dry well/wet well design. Wastewater is conveyed to the lift station by a 16-inch diameter gravity sewer. Because ofthe Hmited wet well size the pumps are controlled by a variable frequency drive. The lift station discharges to a 10-inch diameter force main that conveys the wastewater to the City's Vista Carlsbad Interceptor sewer. On Febmary 1, 2010, Psomas submitted a Final Preliminary Design Report for the HPLS to the City ofCarlsbad. This report included the analysis of four (4) altematives for the replacement of the existing sewer lift station. After intemal meetings between City staff and discussions with Psomas, a final "Hybrid" replacement altemative has been selected which includes various station components from the four altematives presented below in this report. 1.1 Proposed Project Location The proposed project area is approximately 1.2 acres in size located in northwestem San Diego County (Figure 1, Project Location) within the City of Carlsbad. The proposed project site is located on property owned by the City of Carlsbad, on the south side of the Buena Vista Lagoon off Carlsbad Boulevard adjacent to the North County Transit District's rail road track right-of- way, at an elevation of approximately 25 feet above mean sea level. The proposed project site can be found on the United State Geological Survey (USGS) 7.5 minute Topographic San Luis Rey Quadrangle, within the Township 1 IS, Range 4W, Section 6. The project site can be accessed from Carlsbad Boulevard (Figure 2, Site Map).

Main design issues include the following: • Sand & Rags: The New Lift Station will need to provide for a means to easily collect and dispose of collected sand. Sand accumulation can be in excess of several feet per month. The new HPLS will need either a new arrangement or a comminutor or other method to prevent rags from clogging the pumps. • Grease: The new lift station will need to provide the means of controlling the amount of grease entering into the wet well. The City has ciurently adopted a Fats, Oils and Grease (FOG) ordinance, which should reduce the amount of FOG discharged into the wastewater system of the food establishments, but historical grease accumulation is very significant at the lift station. • Holding Capacity: The lift station is adjacent to public beaches. It is desired that the new HPLS have a four hour holding capacity to meet build-out conditions in accordance with the City's 2003 Wastewater Master Plan. • Bioretention Basin: A bioretention basin will be installed in the northem portion of the Project site. An inlet spillway consisting of riprap will allow flow from the concrete swale to enter the bioretention basin. • Odor & Ventilation: The existing lift station has significant odor from the wastewater that needs to be controlled. In addition the ventilation system for maintenance staff needs to meet current code requirements. The new lift station will have a ventilation system that effectively controls odor issues and hazardous gases. • Electrical: The new lift station will have the motor control center and other electrical panels located above the grade to comply with current electrical codes. The design shall consider programmable controllers that can be accessed remotely through SCADA system and laptop computers maintained by on call staff. • Structural: There is concrete spalling and corrosion of the reinforcing steel in the existing wet well. The stmctural design of the new Uft station shall include a PVC liner for the wet well. • Site Security: The new lift station will have a Closed Circuit Camera (CCTV) security system for site security and other measures to meet security requirements. Safe access to and from the site off Carlsbad Boulevard shall be included. PSOMAS 2-4 January 27,2012 • It is anticipated that the existing standby power generator and the building enclosing the generator can be maintained for use and design of the new lift station. On behalf of the City, Psomas developed five altemative project designs to meet the objectives ofthe proposed project and address the design issues described above. These altematives are described below. 2.1 Alternative Project Designs Five altematives, including the preferred alteraative (Altemative 5, Pump Station) have been evaluated and are detailed below. In addition to what is presented under each specific altemative, the following items are the same for each altemative: • New northem paved entrance to station. • Chain link fence with landscape screening around entire site. • CCTV security system. • 15" diameter gravity influent sewer. • 8" diameter force main. • Work required within NCTD ROW. • Temporary bypass coupling in a precast vault located on the force main. • Magnetic flow meter in vault located downstream of bypass coupling on force main. • Sluice gate provided on influent line to station so gravity flow can be stopped for facility cleaning. • Bypass pumping will not be required for any of the altematives. A short shut down of the station will be required though to make the connection to the existing force main. Also, each altemative can be modified to include variable frequency drives (VFDs) on the pumps. A detailed cost breakdown for each of the altematives is provided in the City ofCarlsbad Preliminary Design Report for the Home Plant Lift Station Upgrade (Psomas, August 2009).

Constmction of the proposed project will require grading of most of the existing disturbed portion of the sewer lift station site. The site will provide area for constmction lay down and storage. The existing buildings will be left on-site without modification or demolition. The new building and hardscaping will be added in the existing disturbed portion of the site. Some export of dirt will be required. Approximately 0.66 acres of the site will be disturbed during constmction and then those areas not subject to building or hardscaping will be landscaped with native vegetation. The remaining portion of the site, which is nearest Buena Vista Lagoon, will be left in its natural condition. ii • PSOMAS 2-10 January 27, 2012 The new lift station will be a submersible pump station that will include a below grade, reinforced concrete, rectangular, wet well stmcture. The station will include three pumps mounted on stainless steel guide rails for ease in removing and the wetwell will be PVC lined. Five (5) traffic rated hatches (4x4 feet each) will provide full access to the wet well, allowing Operations & Maintenance staff to maintain pumps and clean the wet well. The wetwell will not contain a comminutor, settling chamber or pre-treatment device. A sluice gate will be provided over the inlet pipe to allow for occasional flushing. Adjacent to the wet well stmcture, there will also be a separate below grade traffic rated valve vault with access hatch containing three (3) swing check valves and three (3) plug valves. 2.1.5.1 Force Main A new force main will be installed parallel to the existing 10" diameter force main to provide redundancy and reduce the amount of low and high points to increase flow velocities. This new force main will most likely be 8" diameter HDPE and will follow an alignment close to the existing one. Current velocities are approximately 3 feet per second (fps), which is believed to cause settling of solids. The new 8" force main will provide for velocities of approximately 5 fps, which is typically adequate to move solids through the pipeline. The new force main will be installed by slant drilling from the proposed sewer lift station site under Carlsbad Boulevard and State Street, surfacing in the landscaped portion of Maxon Brown Park. No sensitive habitat will be disturbed with the installation of the force main. From the park to the terminus ofthe force main at the comer of Laguna Drive and Jefferson Street a 4-foot-wide trench will be required. Within the park, the trench and a 15-foot-wide trenchless pit will create an area of temporary disturbance 20-60 feet wide. Along Laguna Drive a 4 foot wide trench will be required—no other ground disturbance will be needed. The City, following installation ofthe force main, will repave Laguna Drive and replant the disturbed areas of the park. This project will also install a temporary bypass coupling connection, force main isolation valve and magnetic flow meter in precast concrete vaults just outside the valve vault. 2.1.5.2 Pumps and Motors The three (3) submersible pumps will each be rated at 800 gpm at approximately 75' TDH and will have 25 HP, 3-phase, 460 volt, constant speed motors. See attached calculations. (These values are only approximate as the TDH may vary depending on the new force main design. Also, it should be noted that the pumps will need to be evaluated during design to assure they will operate adequately with the existing 10" diameter force main as well.) The pumps will be Flygt, submersible, non-clog with the N impeller or approved equal. City maintenance crews have indicated a preference for Flygt N impeller pumps because they are easy to maintain and do not require a comminutor upstream. 2.1.5.3 Rag, Debris and Sand Removal Based on the higher velocities provided with a new force main, use of N impellers and discussions with City staff, no comminutor, settling chamber or pre-treatment device will be installed. PSOMAS 2-11 January 27, 2012 2.1.5.4 Grease Removal Two options will be provided. 1. Providing access to the wetwell so grease that accumulates can be hosed to a comer of the wet well, removed by a Vactor tmck, and hauled offsite. This is currently how grease at the station is handled, but due to poor access to the existing wet well, this task is difficult for maintenance crews to perform 2. Installing a wetwell spray system. (There are several different systems available and before proceeding with design, Psomas will meet with the City to determine which system should be included.) One system that could be used consists ofa small diameter water tube mounted inside the wetwell and connected to a rotating spray head. Bacteria are mixed with the wash water to break down the grease. When the sewage level inside the wetwell is at its lowest and the walls are most exposed, a solenoid switch can open a valve and allow the spray heads to begin rotating and spraying bacteria laden water on the walls, where it then begins to break down the grease and oil. As the sewage level rises, the bacteria become suspended in the wastewater where its bioremediation is continued. Another system includes a spray nozzle mounted several feet above the high water elevation in the wetwell. This nozzle is cormected either to a dedicated pump or the force main discharge pipe. When activated, the nozzle agitates the surface, breaking up organic and bio-organic matter and delivers dissolved oxygen to the wastewater. Solids sizes are reduced and FOG is kept soluble which minimizes buildup on the walls and equipment. 2.1.5.5 Emergency Storage Four (4) hours of peak flow emergency storage will be provided. At a peak flow rate of 800 gpm, this equates to a volume of 192,000 gallons. This storage will be provided by a combination of facilities including the existing lift station stmcture; the new wet well, the existing gravity system and a new buried concrete stmcture. Sewage will back up into these facilities up to an elevation of 27 feet. This height is based on a review of the collection system upstream, which showed the lowest manhole rim elevation being 28 feet. Allowing 1 foot of freeboard, a maximum elevation of 27 feet was determined to be the highest allowed elevation. 1. Existing Lift Station Drywell/Wetwell: The existing lift station stmcture will remain in place and will be utilized for emergency storage via a connection from an overflow pipe. All appurtenances in the station will be removed. The floor ofthe wetwell will be sloped to the center of the existing access points. STORAGE PROVIDED: 69,200 GALLONS 2. Proposed Wetwell: The proposed wetwell provides a certain amount of storage between the high water elevation of 12 feet and the overflow elevation of 27 feet. STORAGE PROVIDED: 18,500 GALLONS PSOMAS 2-12 January 27, 2012 • 3. Existing Gravity Collection System: Review of the City's sewer system indicates that approximately 45,000 gallons will be stored in the gravity system to elevation 27 feet. STORAGE PROVIDED: 45,000 GALLONS 4. Proposed Concrete Storage Structure: A new, buried, cast in place, reinforced concrete stmcture will be provided similar to the existing stmcture at the North Batiquitos pump station. Two 12" diameter pipelines will provide the overflow and retum connections between the proposed wetwell and proposed concrete storage stmcture. Flap gates will be provided on each pipeline to minimize odors escaping the wetwell. The stmcture will also have a slotted opening and several access ports to provide access to the sloped bottom. STORAGE PROVIDED: 59,300 GALLONS TOTAL STORAGE PROVIDED: 192,000 GALLONS 2.1.5.6 Odor Control The City's preference is for a vent stack, which will be provided. If necessary, the design will provide space for a future odor bed. 2.1.5.7 Bio Retention Basin The City intends to constmct a bio retention pond which will be maintained during the life of the project. Its purpose will be to minimize site mnoff and improve water quality by promoting filtration and infiltration. . 2.1.5.8 Electrical Controls and Building The electrical controls and telemetry will be housed in a new above grade building, approximately 14' by 14'. The existing generator will be removed and the existing underground fuel tank will be abandoned in place. A new diesel generator with fiael storage will be installed in the existing building. PSOMAS 2-13 January 27, 2012 3.0 Methods and Survey Limitations Studies of the biological resources associated with the proposed project site began with a review of available literature followed by a field assessment ofthe project site. The purpose of the field assessment (also referred to herein as field survey) was to determine whether special status plant and wildlife species occur or could potentially occur within or adjacent to the proposed project area. During the field survey, biologists searched for potentially occurring listed and sensitive plant and wildlife species, as well as habitat with the potential to support those species. The timing of the field survey was considered suitable for the identification of most, but not all plant species. Conducting the field survey in the mid-summer decreased the likelihood of detecting fall, winter, spring, and early summer blooming plant species. There were a number of plants in bloom, but there were also a number of plants yet to bloom and a number of plants that had already bloomed and gone to seed. Therefore, an effort was made to determine presence or absence of potentially suitable habitat for those plants that could not be identified at that time. In general, the time of year was favorable for conducting a wildlife survey. The field survey was conducted during the daytime to maximize the detection of most wildlife. Birds represent the largest component of the fauna, and because most birds are active in the daj^ime, diuraal surveys maximize the number of observations of this portion of the fauna. In contrast, daytime surveys usually result in few observations of mammals, many of which may only be active at night. In addition, many species of reptiles and amphibians are secretive in their habits and are difficuh to observe. Many wildlife species are secretive and nocturaal, such as some reptiles, amphibians and small mammals, and therefore assessments of potential presence/absence were made based on habitat, diagnostic signs (burrows, scat, tracks, vocalizations and nests), known records or occurrence within the areas, known range, and habitat utilization from the relevant literature. 3.1 Literature Review 3.1.1 Special Status Species Identification Prior to the field survey, available literature regarding listed, candidate, and sensitive plant and wildlife species was reviewed to identify special status plant and wildlife species having the potential to occur within the proposed project area. Literature reviewed includes the following: • A Field Guide to Western Reptiles and Amphibians, 3^^ ed. (Stebbins 2003). • A Flora of Southern California (Munz 1974). • Buena Vista Lagoon Foundation website (www.buenavistalagoon.org) • Califorma Native Plant Society (CNPS) Inventory of Rare and Endangered Plants of California iCN?S 2011). • City of Carlsbad Habitat Management Plan (Carlsbad 2004) • Field Guide to the Birds ofNorth America, 4* Ed. (National Geographic Society 2002). • Fish and Wildlife Service (http ://criticalhabitat. fws. gov/: USFWS 2011 b). • Mammals of California (Eder 2005). • Mammals ofNorth America (Kays et. al. 2002). PSOMAS 3-1 January 27, 2012 • Special Animals List (CDFG 2011a). • • • Species Accounts from CDFG website (http://www.dfg.ca.gov/wildlife/nongame/genplantsanimals.html; CDFG 2011b). • State and Federally Listed Endangered and Threatened Animals of California (CDFG 2011c). • State and Federally Listed Endangered, Threatened, and Rare Plants of California (CDFG 201 Id). • The California Natural Diversity Data Base for San Luis Rey Quadrangle (CDFG 2011). • The Jepson Manual: Higher Plants of California (Hickman 1993). • The Sibley Field Guide to Birds of Western North America (Sibley 2003). • USFWS list of Endangered and Threatened Species for San Diego County (USFWS 2011a). An inventory of listed, candidate and sensitive plant and wildlife species was derived from the literature review. This, in addition to the query of the CNDDB for reported locations of listed and sensitive plant and wildlife species and sensitive natural communities, identified the known locations of rare, threatened, and endangered species and significant natural communities in the region and assisted in identifying the potential for on-site occurrence ofsuch species. The life history and survey requirements for listed, candidate, and sensitive plant and wildlife species were identified through the literature review, and a query of the USFWS website for threatened and endangered species in San Diego County. The literature review provided a baseline from which to inventory the biological resources potentially occurring on the proposed project property, as well as the surrounding area. Prior to the field surveys, the Califoraia Natural Diversity Data Base (CNDDB), a database that inventories status and locations of rare plants and wildlife in Califomia, was used to identify any sensitive plant communities that may exist in the proposed project area. Psomas conducted a query for the San Luis Rey Quadrangle. The CNDDB identified seven sensitive plant communities that occur within the vicinity ofthe proposed project. 3.2 Field Survey li/lethods Psomas biologists visited the proposed project site on July 07, 2009 and September 3, 2009 to perform a habitat assessment; conduct vegetation surveys; and conduct wildlife and botanical surveys within the City ofCarlsbad Home Plant Lift Station Replacement Project area. These surveys were conducted on foot by Psomas biologists (Dr. Brad Blood and Ms. Cathleen Weigand). Psomas biologists (Dr. Brad Blood and Ms. Cathleen Weigand) re-visited the project site on July 21, 2011 to perform an updated habitat assessment, vegetation survey, and conduct wildlife and botanical surveys within the project area. During the July 21, 2011 site visit, Psomas observed that the previously mapped 0.23-acre area of disturbed Diegan coastal sage scmb and a 0.08-acre area of disturbed habitat (see Section 4.1.5 below) had been removed, and the resulting 0.23-acre area was bare ground with scattered weeds. The City of Carlsbad informed Psomas that the vegetation was removed to provide a laydown and storage area for the Beech Avenue Sewer Replacement project. Psomas remapped this area as disturbed habitat and bare ground for purposes of the HPLS project. Psomas also PSOMAS 3-2 January 27,2012 remapped all ofthe vegetation onsite due to the length of time between the initial site visit and the most recent survey. The HPLS project will not need to mitigate for loss ofthe Diegan coastal sage scmb because the removed area was mitigated for on September 13, 2011 by debiting 0.23 acre (1:1 ratio) from the Lake Calavera Mitigation Parcel. During the field surveys, focus was placed on locating sensitive biological resources including listed and sensitive plant and wildlife species listed above and their habitats, assessing the quality of habitat present on-site for potentially occurring sensitive biological resources, and assessing potential impacts from proposed project activities. The purpose of the field surveys was not to extensively search or undertake directed surveys for every plant species with the potential to occur within the study area, but to ascertain general conditions and identify habitat areas that could be suitable for listed or sensitive plant and wildlife species. The biologists walked the entire proposed project site to allow complete coverage of the entire proposed project area. The biologists paid special attention to those habitat areas that appeared to provide suitable habitat for the species listed above. All plant species encountered during the field surveys were identified and recorded. All common plant species were readily identified by visual characteristic and morphology in the field. Unusual and less familiar plants were later identified using taxonomical guides. Taxonomic nomenclature used in this study follows The ' Je/7.so« Ma«wa/(Hickman 1993). The plant communities on the proposed project site were identified and mapped in the field directly on an aerial photo. Aerial photographs were used to assist in the delineation of plant community boundaries. Biologists searched for sensitive plant communities to see if they occur on the proposed project site. The methods used to detect and identify wildlife included: sight, scat, animal tracks, burrows, nests, and vocalizations. Binoculars were used to aid in the identification of observed wildlife. All wildlife species encountered during the field surveys were identified and recorded. The purpose of the field survey was not to extensively search or undertake directed surveys for every wildlife species occurring within the study area, but to ascertain general conditions and identify habitat areas that could be suitable for listed and sensitive wildlife species. Plant and wildlife field guides and photographs were used to assist with identification of plant and wildlife species during the field surveys. Photographs were taken to document existing conditions within the proposed project area. The potential for listed species occurrence was assessed as low, moderate, or high. i . PSOMAS 3-3 January 27. 2012 4.0 Results Photographs of the proposed project site that were taken during the field surveys can be found in Appendix A, Site Photographs. 4.1 Plant Communities and Non-Vegetated Features This section describes the plant communities and non-vegetated features determined to be present on the proposed project property as a result ofthe literature review and the field survey. Generally, classifications of habitat types or vegetation communities were based on A Manual of California Vegetation, Second Edition (Sawyer et al. 2009) and Preliminary Descriptions of the Terrestrial Communities of California (Holland 1986) with modification to better represent existing conditions in the field. Six plant communities were observed within the vicinity ofthe proposed project area during the field survey (Figure 3, Existing Conditions, and Figure 3A, Existing Conditions: Home Plant Sewer Lift Station Detail). They include: Plant Communities .

During the July 21, 2011 site visit, Psomas biologists observed that the previously mapped 0.23-acre disturbed Diegan coastal sage scmb habitat had been removed. The habitat was removed to provide a laydown and storage area for implementation of the nearby Beech Avenue Sewer Replacement project. This area is currently bare ground with scattered weeds.

Generally, classifications of habitat types or vegetation communities were based on^i Manual of California Vegetation, Second Edition (Sawyer et al. 2009) and Preliminary Descriptions of the Terrestrial Communities of California (Holland 1986) with modifications to better represent existing conditions in the field. 4.1.1 Diegan Coastal Sage Scrub and Disturbed Diegan Coastal Sage Scrub A Manual of Califomia Vegetation, Second Edition (Sawyer et al. 2009) classifies this species assemblage and the associated assemblages among their Califomia sagebmsh scmb shmbland alliance. Preliminary Descriptions of the Terrestrial Communities of Califomia (Holland 1986) classifies this species assemblage as Diegan coastal sage scmb (Element Code 32500). Holland describes coastal sage scmb as low, soft-wooded sub shmbs that are most active in the winter and early spring. Many taxa are facultatively drought-deciduous. Califomia sagebmsh (Artemisia califomica), seacliff buckwheat (Eriogonum parvifolium), coastal goldenbush (Isocoma menziesii), and Califomia encelia (Encelia califomica) are the dominant coastal sage scmb species; however other sage scmb species are often present (Holland 1986). Sawyer et al. describe this Califomia sagebmsh scmb shmbland alliance as including Califomia sagebmsh as the dominant or co-dominant in the shmb canopy with black sage, Califomia enceUa, Califomia buckwheat, among others equally important shmbs in the canopy. Emergent shmbs and trees may be present with a variable ground cover. This series is found from sea level to 1,200 meter MSL. There is no coastal sage scmb within the project site; however there is coastal sage scrab adjacent to the site. In the site vicinity, the coastal sage scmb commimity exhibits high quality habitat. The characteristic plant species of the coastal sage scmb habitat include: Califomia sagebmsh, CaUfomia buckwheat, CaUfomia encelia, wild mustard (Hirschfeldia incana), toyon (Heteromeles arbutifolia), lemonadeberry (Rhus integrifolia), coimnon CaUfomia aster (Corethrogynefilaginifolia [=Lessingiafilaginifolia]), and bromes (Bromus diandrus, B. madritensis spp. rubens). Degraded Diegan coastal sage scmb consists of generally less than 10 percent cover native shmb, sub shmb, and herbaceous species. Degraded Diegan coastal sage scmb supports moderate to high cover of exotic aimuals (approximately 50 percent cover or greater) including tocalote (Centaurea melitensis), wild mustard, Russian thistle (Salsola tragus), wild oat (Avena sativa), and filaree (Erodium botrys). During the 2009 surveys, the degraded Diegan coastal sage scmb habitat within the project area included low-density stands of CaUfomia buckwheat, Califomia sagebmsh, Califomia simflower, sugar bush, with some cover of other native subshmbs or herbaceous species. Native herbs, including perennial western ragweed (Ambrosia psilostachya), telegraph weed (Heterotheca grandiflora), and narrowleaved everlasting (Gnaphalium angustifolium) were also present at relatively low cover. PSOMAS 4-4 January 27,2012 4.1.2 Freshwater Marsh A Manual of California Vegetation, Second Edition (Sawyer et al. 2009) classifies this plant assemblage among their Cattail marshes herbaceous alliance. Preliminary Descriptions of the Terrestrial Communities of Califomia (Holland 1986) classifies this species assemblage as Coastal and Valley Freshwater Marsh (52410). This commimity is dominated by perennial, emergent monocots, in primarily permanently flooded or regularly flooded areas. Holland describes freshwater marsh as dominated by perennial, emergent monocots 4 to 5 meters tall, often forming a dense closed canopy. Cattail (Typha spp.) mshes (Juncus spp.), and sedges (Scirpus spp.) are the dominant plant species within this community. Site factors include quite areas (lacking significant current), permanently flooded by freshwater, with prolonged saturation permitting the accumulation of deep, peaty soils. Sawyer et al. describe this cattail marsh alliance as a commimity of broadleaf cattail as the dominant or co-dominant in the herbaceous layer with grasses, (Agrostis spp., Distichilis spicata, among others) Juncus spp., and bulmsh species, among others dominating the community. Freshwater marsh was observed along the perimeters of the Buena Vista Lagoon adjacent to the HPLS project area. The characteristic plant species of the freshwater marsh habitat include: narrowleaf cattails (Typha domingensis), bulmsh (Scirpus sp.), and spiny msh (Juncus acutus), among others. Freshwater marsh is considered a Water of the United States, and as such is under the jurisdiction ofthe USACOE (pursuant to Section 404 ofthe federal Clean Water Act) and the Califomia RWQCB (pursuant to Section 401 of the federal Clean Water Act and the Califoraia Coastal Commission). In addition, it is considered a Waters of the State and as such is under the jurisdiction of the CDFG (pursuant to Section 1602 ofthe Califoraia Fish and Game Code). 4.1.3 Open Water/Buena Vista Lagoon Buena Vista Lagoon sits to the north of the HPLS project area. Open water/ Buena Vista Lagoon is considered a Water of the United States, and as such is under the jurisdiction of the USACOE (pursuant to Section 404 ofthe federal Clean Water Act) and the CaUforaia RWQCB (pursuant to Section 401 ofthe federal Clean Water Act and the CaUforaia Coastal Commission). In addition, it is considered a Waters ofthe State and as such is under the jurisdiction of the CDFG (pursuant to Section 1602 of the CaUforaia Fish and Game Code). 4.14 Ornamental This vegetation community is composed of different stands of oraamental species that appear to have persisted without irrigation. At the project site omamental vegetation includes red gum eucalyptus trees (Eucalyptus camaldulensis), loUypop tree (Myoporum laetum), golden wattle (Acacia longifolia), and other omamental species. PSOMAS 4-5 January 27,2012 4.1.5 Disturbed and Developed Disturbed habitat refers to unpaved areas including dirt or gravel roads, parking areas, or other surfaces that have been subjected to continuous mechanical disturbance (i.e., moving and parking motor vehicles or other mechanized equipment). Disturbed habitat is found on the project site adjacent to the pump yard and along tiie perimeters ofthe site. Developed land describes areas occupied by stmctures, paving and other impermeable surfaces that carmot support vegetation. Developed areas consist primarily of the paved and dirt access roads, and pump yard. 4.2 Plants A standard in the professional practice of botany is to conclude species absence in only a few limited instances: • Where the species is detectable without flowers or fruits (e.g., pereimial shmbs with distinctive vegetative features). • Suitable habitat is clearly absent. • Nvmierous surveys over many years have not detected the species. In general and outside of these limited cases, even with field surveys, botanists assess probability of occurrence rather than make a definitive conclusion about species presence or absence. Failure to detect the presence of the species is not definitive, and may be due to variable effects associated with fire, rainfall pattems, and/or season. For example, plant species with a moderate potential for occurrence are considered to be those for which habitat is present, the proposed project is within the known range of the species, and one or more surveys did not detect the presence of the species. The timing of the field surveys was considered suitable for the identification of most, but not all plant species. Conducting the field surveys in the mid-summer decreased the detection of fall, winter, spring, and early summer blooming plant species. There were a number of plants in bloom, but there were also a number of plants yet to bloom and a number of plants that had already bloomed and gone to seed. Therefore, an effort was made to determine presence or absence of potentially suitable habitat for those plants that could not be identified at that time. A complete list of plant species observed on the proposed project site during the field surveys is provided below in Table 6, Plant Species Observed During the Field Surveys.

They provide the primary plant productivity upon which wildlife depends, along with nesting and denning sites, escape cover and protection from adverse weather. Many of the wildlife species that occur in the area use several ofthe plant communities to obtain all their life history needs. In general, more complex natural communities, with a greater number of vegetation layers and a greater number of plant species, provide higher value wildlife habitat than less complex vegetation communities. More complex communities have a greater number of niches for wildlife and usually support a greater number of animal species than less complex communities. Although simple communities may support few wildlife species, they may provide habitat for great numbers of those few species. A standard in the professional practice of wildlife biology is to conclude species absence in only a few limited instances. • Where the species known range and historic range is over 25 miles from the project site. • Suitable habitat is clearly absent. • Numerous surveys over many years have not detected the species. In general and outside of these limited cases, even with field surveys, wildlife biologists assess probability of occurrence rather than make definitive conclusions about species presence or absence. Failure to detect the species is not definitive, and may be due to variable effects associated with fire, rainfall patteras and/or season. For example, wildlife species with a moderate potential for occurrence are considered to be those for which habitat is present, the project is within the known range of the species, and one or more surveys did not detect the species. During the field surveys, many species of wildlife that could potentially utilize the proposed project site may not have been present because they occur only on a seasonal basis. Many species are nocturaal, move about a territory, or may have become dormant for the season. A PSOMAS 4-9 January 27, 2012 single day survey cannot be used to conclusively determine absence except when potentially suitable habitat can be determined to be absent. However, the potential for the site to provide suitable habitat for special status species was evaluated. A complete Ust of wildlife species observed in the proposed project area during the field surveys is provided below in Table 7, Wildlife Species Observed During the Field Surveys.

These plant species are listed below. • San Diego thom-mint (Acanthomintha ilicifolia) • Dwarfhm ambrosia (Ambrosia pumila) • Del Mar manzanita (Arctostaphylos glandulosa ssp. crassifolia) • Thread-leaved brodiaea (Brodiaea filifolia) • San Diego button-celery (Eryngium aristulatum var. parishii) 4.4.2 Wildlife As a result of the literature review and agency consultation, nine wildlife species listed as endangered, threatened or candidate pursuant to the federal or state Endangered Species Acts PSOMAS 4-10 January 27, 2012 were identified as having the potential to occur within or near the proposed project area or in the vicinity ofthe proposed project area. These wildlife species are listed below. • Tidewater goby (Eucyclogobius newberryi) • Light-footed clapper rail (Rallus longirostris levipes) • Westem snowy plover (Charadrius alexandrinus nivosus) • Califoraia least tera (Sternula antillarum browni) • Southwestem flycatcher (Empidonax traillii extimus) • Least Bell's vireo ( Vireo bellii pusillus) • Coastal Califomia gnatcatcher (Polioptila californica califomica) • Belding's savannah sparrow (Passerculus sandwichensis beldingi) • Stephen's kangaroo rat (Dipodomys stephensi) 4.5 Sensitive Species 4.5.1 Plants Sixteen sensitive plant species were identified from the literature review and agency consultation as having the potential to occur within the proposed project area or in the vicinity of the proposed project area. These sensitive plant species are listed below. Califoraia adolphia (Adolphia califomica) South coast saltscale (Atriplexpacifica) Davidson's saltscale (Atriplex serenana var. davidsonii) Wart-stemmed ceanothus (Ceanothus verrucosus) Smooth tarplant (Centromadia pungens ssp. laevis) Orcutt's pincushion (Chaenactis glabriuscula var. orcuttiana) Summer holly (Comarostaphylis diversifolia ssp. diversifolia) Sea dahlia (Coreopsis maritima) Blochman's dudleya (Dudleya blochmaniae ssp. blochmaniae) Sticky dudleya (Dudley viscida) Sand-loving wallflower (Erysimum ammophilum) Cliff spurge (Euphorbia misera) Palmer's grapplinghook (Harpagonellapalmeri) Mud nama (Nama stenocarpum) Coast wooly-heads (Nemacaulis denudate var. denudate) Nuttall's scmb oak (Quercus dumosa) 4.5.2 Wildlife Eighteen sensitive wildlife species were identified from the literature review and agency consultation as having the potential to occur within or in the vicinity ofthe proposed project area. These sensitive wildlife species are listed below. PSOMAS 4-11 January 27, 2012 V,. Southwestern pond turtle (Emys marmorata pallida) Coast (San Diego) homed Uzard (Phrynosoma coronatum blainvillii) Orange-throated whiptail (Aspidoscelis hyerythra) Northem red-diamond rattlesnake (Crotalus ruber ruber) White-faced ibis (Plegadis chihi) White-tailed kite (Elanus leucurus) Northem harrier (Circus cyaneus) Cooper's hawk (Accipiter cooperii) Califomia homed lark (Eremophila alpestris actia) Coastal cactus wren (Campylorhynchus brunneicapillus sandiegensis) Yellow warbler (Dendroica petechia brewsteri) Yellow-breasted chat (Icteria virens) Southem Califoraia mfous-crowned sparrow (Aimophila ruficeps canescens) Pallid bat (Antrozous pallidus) Pocketed free-tailed bat (Nyctinomops femorosaccus) San Diego black-tailed jackrabbit (Lepus californicus bennettii) Northwestera San Diego pocket mouse (Chaetopidus fallax fallax) San Diego desert woodrat (Neotoma lepida intermedia) 4.6 Listed, Candidate, and Sensitive Species Having the Potential to Occur The plant and wildlife species listed above were assessed for their potential to occur within the proposed project area based on habitat requirements, availability and quality of suitable habitat, and distribution. A number of plant and wildlife species identified in the literature review were determined to have no potential to occur within the proposed project area because the proposed project area does not contain suitable habitat, is located out ofthe species' known geographic range, or is located out of the species' known elevation range limits. A table describing species having the potential to occur within the Project area is found in Appendix A, Special Status Species. During the field surveys, the potential for species to occur was assessed as low, moderate, or high based on the following criteria: • Low: Species with a low potential for occurrence are those for which the proposed project area is on the boimdary of the known range ofthe species, or those for which the proposed project area is within the boundary of the known range of the species and for which suitable habitat in the proposed project area is not known to be used by the species, or for which there are no known recorded occurrences ofthe species within or adjacent to the proposed project area. • Moderate: Species with a moderate potential for occurrence are those for which habitat is present, the proposed project is within the known range of the species, and one or more surveys did not detect the species. No nearby occurrences are known. Failure to detect the PSOMAS 4-12 January 27, 2012 f" species is not definitive, and may be due to variable effects associated with fire, rainfall patteras and/or time of year. • High: Species with a high potential for occurrence are those for which habitat is present, the proposed project is within the known range ofthe species, and the species has been observed in similar habitat in the region by a qualified biologist. 4.6. f Plants 4.6.1.1 Listed Endangered, Threatened, Candidate, and State Rare Plant Species No plant species listed as endangered, threatened, candidate, or state rare pursuant to the federal or state Endangered Species Act were observed in the proposed project area during the field surveys. However, because of the time of year in which the surveys took place, a habitat assessment was performed for potentially suitable habitat conditions to support listed plant species, especially for annual species that appear above ground in a vegetative stage earlier or later in the year. As a result of the field surveys and the literature review, it was concluded that no listed plant species have potential to occur on the proposed project area (Appendix A). 4.6.1.2 Sensitive Plant Species No plant species designated as sensitive or locally important were observed within the proposed project area during the field surveys. However, because of the time of year in which the surveys took place, a habitat assessment was performed for potentially suitable habitat conditions to support sensitive plant species, especially for annual species that appear above groimd in a vegetative stage earlier or later in the year. As a result ofthe field surveys and the literature review, it was concluded that no sensitive plant species have more than a low potential to exist On or adjacent to the proposed project site (Appendix B). 4.6.2 Wildlife 4.6.2.1 Listed Endangered, Threatened, and Candidate Wildlife Species No wildlife species listed as endangered, threatened or candidate pursuant to the federal or state Endangered Species Acts or suitable habitat were observed within or adjacent to the proposed project area during the field surveys. As a result of the field surveys and the literature review, it was concluded that no listed wildlife species have potential to occur on the proposed project area (Appendix B). PSOMAS 4-13 January 27,2012 o 4.6.2.2 Sensitive Wildlife Species No sensitive wildlife species were observed within or adjacent to the proposed project area during the field surveys. As a result of the field surveys and the literature review, it was concluded that no sensitive wildlife species have more than a low potential to exist on or adjacent to the proposed project area. 4.6.3 Sensitive Plant Communities Prior to the field surveys, the Califoraia Natural Diversity Data Base (CNDDB), a database that inventories status and locations of rare plants and wildlife in Califomia, was used to identify any sensitive plant communities that may exist in the proposed project area. Psomas conducted a query for the San Luis Rey Quadrangle. The CNDDB identified seven sensitive plant communities that occur within the vicinity ofthe proposed project. These sensitive plant commimities include: • San Diego Mesa Hardpan Vemal Pool • Southem Coastal Salt Marsh • Southera Cottonwood Willow Riparian Forest • Southem Maritime Chaparral • Southera Riparian Forest • Southem Riparian Scmb • Southem Sycamore Alder Riparian Woodland Sensitive habitats are those that are considered to support unique vegetation communities, sensitive plant and/or wildlife species, or function as corridors for wildlife movement. The seven sensitive habitats identified by the CNDDB as occurring within the proposed project vicinity were not observed on the proposed project area. 4.6.4 Jurisdictional Wetlands No jurisdictional wetlands were mapped within the project property. The open water/Buena Vista Lagoon and freshwater marsh habitat is located north, adjacent to the project property. No impacts to the lagoon or surrounding freshwater marsh habitat will be impacted with implementation of the proposed project. 4.6.5 Wildlife Movement Corridors The project site is located along Carlsbad Boulevard and bordered on three sides by development. However, the Buena Vista Lagoon and the railroad right-of-way border the site to the north and west respectively. Currently the site is minimally developed as a lift station. The developed portion ofthe existing Uft station is at the southem end of the site nearest the developed neighboring areas, and the remainder ofthe site is disturbed vegetation and landscaping. The current condition ofthe site does not prevent its use by wildlife as they use the railroad right-of-way to move north and south through this area. But, the disturbance from trash and itinerant humans lessens the value of the site for wildlife. PSOMAS 4-14 January 27,2012 The railroad right-of-way located immediately west of the project site and the native vegetation that borders this right of way by the project site provides a potential corridor for local wildlife such as coyotes, skunks, domestic and feral cats, dogs, etc. The railroad also passes through another important ecological area, Batiquitos Lagoon, located south of the project site, and hence can provide a corridor between the two lagoon areas. Also, from the project site to the west there is open space that provides a connecting open space to the coast. Much of the railroad right-of- way passes through heavily developed areas both to the north and south, which reduces its value as a corridor, but does not negate that value. PSOMAS 4-15 January 27 2012 5.0 Evaluation of Project Impacts This section discusses potential impacts that will result from the proposed project activities. Under each section, potential permanent and temporary impacts are discussed. Permanent impacts are those which remove the resource, such as the removal of vegetation as a result ofthe proposed project. Temporary impacts include those that result from constmction activities, but once alleviated following constmction will allow the resource to re-establish. Four altemative project designs and a fifth final "Hybrid" replacement altemative/preferred alteraative have been prepared and are described below. The proposed project designs will permanently impact biological resources; as well, temporary impacts are anticipated from constmction activities. A mitigation approach has been recommended to minimize those potential impacts, and shall be incorporated into the project design as applicable. Best Management Practices (BMPs) are discussed in the following section. Approximate impacts for the preferred are listed below in Table 8, Potential Permanent and Temporary Impacts to Plant Communities and Non- Vegetated Features.

The approximate total acreages of plant communities that may be permanently or temporarily impacted by proposed grading activities are listed above in Table 8. The future conditions footprint that would result from implementation of the proposed project is shown in Figure 5, Future Conditions: Preferred Alternative, and Figure 5A, Future Conditions: Home Plant Sewer Lift Station Detail.

As a result of the field surveys and the literature review, it was concluded that no listed plant species have more than a low potential to exist on or adjacent to the proposed project area due to lack of suitable habitats, soils and other factors such as distribution and elevation ranges; therefore no permanent or temporary impacts to listed, endangered, threatened, candidate or state rare plant species are anticipated as a result of implementation of the proposed project and no mitigation is needed. 5.3 Potential Impacts to Sensitive Plants No plants designated as sensitive by the CNPS were observed during the field surveys and none are known or expected to occur within the proposed project site. As a result of the field surveys and the literature review, it was concluded that no sensitive plant species have more than a low potential to exist on or adjacent to the proposed project site due to lack of suitable habitats, soils and other factors such as distribution and elevation ranges; therefore no permanent or temporary impacts to sensitive plant species are anticipated as a result of implementation ofthe proposed project. 5.4 Potential Impacts to Listed Wildlife No wildlife listed as endangered, threatened or candidate pursuant to the federal or state Endangered Species Acts were observed during the field surveys or are known to occur within the proposed project site. As a result of the field surveys and the literature review, it was concluded that no listed wildlife species have more than a low potential to exist on or adjacent to the proposed project site due to lack of suitable habitats, soils and other factors such as distribution and elevation ranges; therefore no permanent or temporary impacts to listed wildlife species are anticipated as a result of implementation of the proposed project. No coastal Califoraia gnatcatcher has been observed or reported from the proposed project site. However, a population is known from approximately 3,000 feet away at 1-5 and Buena Vista Lagoon, to the east ofthe proposed project site. The intervening habitat is freshwater marsh, other wetland habitat, landscaping, and residential and commercial development. Because there is no onsite habitat and because no coastal sage scmb habitat will be impacted by the proposed project, no impacts to coastal Califomia gnatcatcher would result from implementation of the Proposed Project. 5.5 Potential Impacts to Sensitive Wildlife No sensitive wildlife species were observed during the field surveys. As a result of the field surveys and the literature review, it was concluded that the identified potentially occurring sensitive wildlife species have no more than a low potential to exist on the proposed project site due to lack of suitable habitats, soils and other factors such as human disturbance. Therefore, no PSOMAS 5-6 January 27,2012 impacts would occur to sensitive wildlife species as a result of implementation ofthe Proposed Project. 5.6 Potential Impacts to Nesting Birds Nesting birds are protected under The Migratory Bird Treaty Act (MBTA). The MBTA protects all common wild birds found in the United States except the house sparrow (Passer domesticus), European starling (Stumus vulgaris), rock pigeon (Columba livia), and resident game birds such as pheasant, grouse, quail, and wild turkey (Meleagris gallopavo). Resident game birds are managed separately by each state. The MBTA makes it unlawful for anyone to kiU, capture, collect, possess, buy, sell, trade, ship, import or export any migratory bird including feathers, parts, nests, or eggs. CDFG code 3503 makes it illegal to destroy any birds' nest or any birds' eggs that are protected under the MBTA. Code 3503.5 fiuther protects aU birds of prey, such as hawks and owls, and their eggs and nests from any form of take. The proposed project has the potential to directly impact nesting birds through the removal of vegetation and constmction activities on the project site, in Maxon Brown Park, and along Laguna Drive. Indirect impacts to breeding birds could occur from increased noise, lighting, and dust during constmction, which could adversely affect the breeding behavior of some bkds. These impacts can be reduced with incorporation of the recommended mitigation measures. Project related disturbance of active nests, either direct or indirect, if identified, will require concurrence with CDFG and the MBTA division of USFWS. Pursuant to the MBTA and CDFG codes, removal ofany trees, shmbs or any other potential nestmg habitat should be conducted outside ofthe nesting season. The nesting season typically occurs between early Febmary and August, but can vary slightly from year to year. Conducting constmction activities outside of the nesting season would avoid impacts to nesting migratory birds and raptors. Project-related disturbance of active nests, either direct or indirect, if identified, will require concurrence with CDFG and the MBTA division of USFWS. 5.7 Potential Impacts to Wildlife Corridors The project site is located along Carlsbad Boulevard and bordered on 3 sides by development. However, the Buena Vista Lagoon and the Railroad right-of-way border the site to the north and west respectively. Currently the site is minimally developed as a lift station. The developed portion of the existing lift station is at the southem end ofthe site nearest the developed neighboring areas, and the remainder ofthe site is disturbed vegetation and landscaping. The current condition of the site does not prevent its use by wildlife as they use the railroad right-of- way to move north and south through this area. However, the disturbance from trash and itinerant humans lessens the value of the site for wildlife. The railroad right-of-way located immediately west of the project site and the native vegetation that borders this right of way by the project site provides a potential corridor for local wildlife such as coyotes, skunks, domestic and feral cats, dogs, etc. The railroad also passes through another important ecological area, Batiquitos Lagoon, located south of the proposed project site, and hence can provide a corridor between the two lagoon areas. Also, from the project site to the PSOMAS 5-7 January 27,2012 west there is open space that provides a connecting open space to the coast. Much of the railroad right-of-way passes through heavily developed areas both to the north and south, which reduces its value as a corridor. The project will not have a negative effect on wildlife corridors. 5.8 Adjacency Standards The City of Carlsbad HMP requires that projects developed or undertaken near ecologically sensitive areas comply with adjacency standards. These standards were developed to protect sensitive natural resources from degradation or damage from the development process (i.e., constmction activity) or from the use of the site following development from direct and indirect human activities. The HPLS Project site lies directly adjacent to Buena Vista Lagoon, which is a designated environmentally sensitive area (ESA); as such, HPLS Project activities must comply with the HMP's adjacency standards. The adjacency standards are divided into five different areas: • Fire management • Erosion Contiol • Landscaping Restrictions • Fencing, signs, and lighting • Predator and exotic species control 5.8.1 Flre Management The Fire Management section requires the identification of potential fiiel reduction zones or fire breaks; development of feasible fuel reduction zones and firebreaks; management of fiiel loads in smaller fragmented preserves, and active fire management in the larger preserve areas. The HPLS project is bordered by Carlsbad Boulevard and the BNSF Rail Road right-of-way and the lagoon. These barriers provide natural firebreaks to prevent fires from buming onto the site from another area and also provide barriers to fires that may start on-site. In addition, the proposed bio retention basin is between Buena Vista lagoon and the site and will provide an extra measure of fire safety between the site and Buena Vista lagoon. There are no sensitive biological resources on-site and the driveway and large paved area proposed for the site would allow easy access to fire fighters and equipment if needed. The site is small and will be planted with native landscaping. Because ofthe small area of landscaping and the large area of hardscaping there is no necessity for fuel modification zones. To maximize fire protection, the landscaping designer will use, to the extent practical, fire resistant native plants in the landscaping plan. PSOMAS 5-8 January 27,2012 5.8.2 Erosion Control The Erosion Control section requires the identification of erosion priority areas, development of an erosion contiol plan and requires that slope stability and drainage toward preserve areas be addressed. The HPLS site is flat and without any steep slopes within the constmction zone. There is one slope between the constmction area and the lagoon. This area is covered with native coastal sage scmb and would not be impacted by the project, so erosion is not a concem for this area. There are no areas of special concem for erosion control within the constraction zone for the proposed project. The contiactor will develop an erosion contiol plan that will be approved by the City prior to the start of constmction. The plan must include BMPs to address the potential for run-off and erosion from the constmction activities to prevent sediment and silts from entering Buena Vista Lagoon. The site will be graded and sloped so that mn-off is directed away from Buena Vista Lagoon. Because ofthe grziding and extent of hardscaping, erosion will not be an issue with this project once it is complete. 5.8.3 Landscaping Restrictions This section prohibits the introduction of non-native invasive plants near preserve areas, and prohibits horticultural practices that may change site conditions that could promote the invasion of preserve areas by non-native invasive plants. This section also seeks to prevent the genetic contamination of native plants by native cultivars in preserve areas. The HPLS site will be landscaped with native plants appropriate for the site. The plant palette will be based on the biological reports list of native plants that occur on-site and the biologist's recormnendations of local plants that would be appropriate for planting at the site. The use of native plants for the site will enable the City to limit the watering of landscaping on- site. Watering and irrigation will be designed so as to not cause nm-off of water of any fertilizers into the adjacent coastal sage scmb and Buena Vista Lagoon. 5.8.4 Fencing, Signs, and Lighting This section seeks to control the use of fencing, signs, and lighting to limit (to the extent practical) the impacts of these features on preserve areas and to provide guidance when these features are necessary. 5.8.4.1 Fencing The HPLS site is not within a preserve and is located outside the 100-foot wetland buffer. Because of the nature of the facility, fencing will be necessary to keep the pubUc and vandals from the site. The fencing will be designed to provide protection of the site and be attiactive to PSOMAS 5-9 January 27,2012 the public, especially along Carlsbad Boulevard. Because of the site's location, the fencing will not interfere with the movement of wildlife to and from the Lagoon or other open space areas, nor will it interfere with the railroad right-of-way immediately adjacent to the site. 5.8.4.2 Signs No signage is plaimed except for the minimal needed to identify the site and wam the public from entering. No other signage is deemed necessary for this project. 5.8.4.3 Lighting Lighting is plaimed for the site and will be designed to keep excess illumination away from the preserve area by shielding nearby Ughts so that the illumination is directed downward. 5.8.5 Predator and Exotic Species Control The predator and exotic species contiol section seeks to limit and contiol the invasion of preserve areas by non-native wildlife and plants. Non-native plants have been addressed above. This section is not directly applicable to this project as this section addresses measure to take within preserves. However, the use of fencing and native landscaping will assist, but not prevent the site's use by non-native wildlife such as house cats or native predators, such as coyotes and bobcats. The City will, to the extent practical, monitor the site for use by the species and inform the appropriate city or state department should removal become necessary, such as when a species has taken up residence on-site. 5.9 Additional Conservation Measures for Properties Within the Coastal Zone 5.9.1 Environmentally Sensitive Areas The proposed project will not dismpt or impact the Lagoon. During constmction the contractor will implement standard BMPs and develop erosion control plans to prevent impact to Buena Vista Lagoon. The City will monitor the contractor to ensure that the contiactor is complying with the BMPs and other work restiictions, which can include, but are not limited to: • Resfrict workers to the constmction zone • Implement a litter control program • Maintain a port-a-let on-site • No pets at the work site 5.9.2 Coastal Sage Scrub There is no coastal sage scmb in the impact area for the proposed project. During the July 21, 2011 site visit, Psomas observed that a previously mapped 0.23-acre area of disturbed Diegan coastal sage scmb and a 0.08-acre area of disturbed habitat had been removed, and the resulting PSOMAS 5-10 January 27,2012 0.23-acre area was bare ground with scattered weeds. The City of Carlsbad informed Psomas that the vegetation was removed to provide a laydown and storage area for the Beech Avenue Sewer Replacement project. Psomas remapped this area as disturbed habitat and bare ground for purposes of the HPLS project. Psomas also remapped all ofthe vegetation onsite due to the length of time between the initial site visit and the most recent survey. The HPLS project will not need to mitigate for loss ofthe Diegan coastal sage scmb because the removed area was mitigated for on September 13, 2011 by debiting 0.23 acre (1:1 ratio) from the Lake Calavera Mitigation Parcel. While there is no coastal sage scmb habitat in the impact area for the proposed project, coastal sage scmb habitat does exist adjacent to the project site. Fencing or flagging will be used to mark the limits of allowable work areas to prevent impacts to adjacent coastal sage scmb. 5.9.3 Oak Woodland No oak woodlands occur on-site or are nearby the project area. 5.9.4 Streams No stieams are located on the proposed project site or adjacent to the proposed project site. 5.9.5 Ephemeral Drainages No ephemeral drainages occur on-site or adjacent to the site. 5.9.6 Wetlands The adjacent Buena Vista Lagoon is bordered by freshwater wetlands. No wetlands will be impacted by the proposed project. The project will take place on the existing lift station property and the contractor will implement BMPs as required by the City to ensure no impacts to wetlands occur during the constmction of the project. 5.9.6.1 Wetland Mitigation Requirements No impacts will occur to wetlands and therefore no mitigation is necessary. 5.9.7 No Net Loss of Habitat The proposed project will not impact any natural habitats including coastal sage scmb. The project activities are planned to take place on currently disturbed land and developed areas within the project site. The force main replacement will temporarily impact landscaped areas in Maxon Brown Park but these areas will be replaced in kmd. Therefore, there will be no net loss of habitat as a result of implementation of the proposed project. PSOMAS 5-11 January 27,2012 5.9.8 Upland Habitat Mitigation Requirements The proposed project will not impact any coastal sage scmb habitat. The project activities are planned to take place on currently disturbed land and developed areas within the project site. The force main replacement will temporarily impact landscaped areas in the park but these areas will be replaced in kind. Therefore there will be no net loss of upland habitat as a result of implementation of the proposed project and no mitigation is necessary. 5.9.9 Highly Constrained Properties The proposed project site lies next to Buena Vista Lagoon. In Maxon Brown Park the work area is within 100 feet ofthe wetland edge. However, this area is akeady highly landscaped and is not high quality habitat. In addition, the recommended BMPs will ensure that no sediment enters the wetland. The proposed project will not change the use of Buena Vista Lagoon nor will the project impact the lagoon. 5.9.10 Buffers and Fuel Modification Zones The nearest ESHA is Buena Vista Lagoon. The project will maintain a buffer between the wetland edge of the freshwater marsh and the developed portion of the proposed project. 5.9.11 Grading and Landscaping Requirements The proposed project's grading plan was designed to conform to the City's model grading ordinance in the City's Master Drainage Plan. It is anticipated that grading will occur outside of the October 1 to April 1 rainy season. Because it is a small site grading may be able to be accomplished in 2 to 3 weeks. Any graded areas that need to be left for longer than 1 week will be covered and stabilized to prevent erosion. The length of the constmction project may take as long as one year. 5.9.12 City Owned Lands Adjacent to Macario Canyon and Veterans Memorial Park Not applicable to this project. The project site is not adjacent to either of these two features. 5.9.13 Other Parcels - Specific Habitat Protection Standards Not applicable as the proposed project does not occur within Management Zones 20 or 21. 5.10 Mitigation Measures This section includes a recoinmended approach to mitigation and associated measures due to proposed project activities and subsequent impacts. Constmction of the proposed project has been designed to avoid and minimize impacts to biological and water resources. Avoidance measures are proposed as the primary approach to mitigation. PSOMAS 5-12 January 27,2012 Within the Coastal Zone, protective buffers need to be a minimum of 50 feet in width surrounding riparian habitats and 100 feet in width surrounding jurisdictional wetlands. Pursuant to Condition 7-11 ofthe HMP, the protective buffer for wetlands and riparian areas possessing an unvegetated bank or steep slope (>25%) will be measured from the top of the bank or steep slope rather than the edge of habitat, unless there is at least 50 feet between the riparian or wetland area and the toe of the slope. If the toe ofthe slope is less than 50 feet from the wetland or riparian area, the buffer will be measured from the top of the slope. 5.10.1 Mitigation Recommendations for Coastal California Gnatcatcher No direct impacts to coastal Califomia gnatcatchers are expected because there is no suitable habitat on the proposed project site. However, there is adjacent potentially suitable coastal sage scrab habitat adjacent to the site. Therefore, it is recommended that ground-disturbing activities take place outside ofthe recognized nesting season, if practical. The nesting season typically occurs between early Febmary and August, but can vary slightly from year to year. If ground- disturbing activities must occur within the recognized nesting season, then pre-constmction nesting bird surveys will be performed to identify any nests that may be impacted by constmction activities. Surveys for coastal Califomia gnatcatchers will include the project site and a 500 foot buffer area surrounding the HPLS site. If any active nests are located within the proposed disturbance area or within 500 feet of ground disturbing activities, a 500 foot buffer area will be flagged around the nest and no activity will be allowed in the buffer area until nesting is completed. The City will immediately stop work in the area and consult with the US Fish and Wildlife Service and CaUforaia Department of Fish and Game on stiategies to continue work and avoid disturbance to these species while nesting. Potential measures may include sound abatement measures for equipment and monitoring by a biologist until nesting is complete. 5.10.2 Mitigation Recommendations for Nesting Birds and Raptors If constmction activities occur within the recognized nesting season, the City will have a qualified biologist perform a survey for nesting birds and raptors. The survey will be performed at least 14 days prior to the start of ground and vegetation disturbance. The survey area will include the proposed project site and the surrounding 500 feet, the force main aUgnment through Maxon Brown Park and out 500 feet from the proposed edge of disturbance along Laguna Drive. The results of the survey wiU be reported to the City in the form of a memorandum. If any nesting bkds are identified within 300 feet of the proposed project activities or nesting raptors within 500 feet of the proposed project activities, the biologist will GPS the location of the nest site and define a 300 to 500 -foot no-work buffer around the nest site, as appropriate. The biologist and City will initiate consultation with CDFG and USFWS to determine if work can occur within the buffer zone without disturbance to the nest, for example, an on-site biological monitor to monitor active nest(s) during constmction with stop work authorization would be an appropriate measure. PSOMAS 5-13 January 27,2012 5.11 Best Management Practices Constmction of the proposed project has been designed to limit potential impacts to biological resources and water quality. The following BMPs are designed to protect riparian and wetland habitats and associated sensitive biological resources during constmction (Guidelines for Wetiand and Riparian Buffers April 9, 2010). • Erosion and Sediment Contiol: Appropriate minimization and avoidance measures will be installed within the riparian/wetland buffer to prevent discharge of sediment laden stormwater to the riparian zone or wetland during constmction, as outlined in a Storm Water Pollution Prevention Plan (SWPPP). This will include constmction ofa bio retention pond, which will be maintained during the life of the project. Its purpose will be to minimize site ranoff and improve water quality by promoting filfration and inflltration. • Erosion and Sediment Control: Stabilize the banks around riparian buffer crossings and monitor crossings after severe storm and flooding events to determine if excess sedimentation is occurring. • Drainage: When the buffer receives flow directly from an impervious area, design curb cuts or spacers to spread runoff evenly over the riparian buffer area. • Vegetation: Minimize amount of existing vegetation that is disturbed for constmction. • Light Abatement: Although discouraged, if nighttime constmction is unavoidable, stationary lighting shall be shielded and directed away from riparian/wetland areas and buffers. • Noise Abatement: Constmction noise shall not exceed 60dB Leq within the riparian/wetland habitat and buffer. If riparian/wetland habitat or buffer is occupied by sensitive species, species-specific conditions pursuant to the HMP and state and federal laws, must be met. Dust Control: Standard dust control measures, such as street-sweeping and the use of water tmcks, shall be employed as necessary during constmction of all new facilities. • Hazardous Materials: No hazardous materials or petiochemicals may be disposed ofor stored within any portion of mapped riparian/wetland buffer, or within 100 feet of riparian or wetland habitat.

The subject site is located at the City of Carlsbad Home Plant Sewer Lift Station, 2359 Carlsbad Boulevard, in Carlsbad, Califomia (Figure 1). The purpose of our study was to evaluate the infiltration capacity of the subsurface soils in the area of the proposed infiltration basin (Figure 2). This report presents our findings regarding the inflltration capacity of the soils at the locations evaluated. SCOPE OF SERVICES Our scope of services included the following: • Reviewing background information including available geologic and topographic maps, and a geotechnical report for the Home Plant Sewer Lift Station performed by Ninyo & Moore (August 2009). • Performing a field recoimaissance to observe the site conditions and mark out the proposed infiltration test holes. • Notification of Underground Service Alert (USA) to locate potential buried underground utilities in the vicinity of the infiltration test locations. 25 5710 Ruffin Road • SanDiego, Califbmia 92123 • Phone {858} 576-1000 • Fax(858) 576-9600 SanDiego • Irvine • Los/^getes • RanchoCucarnonga • OaWand » SanRandsco • Sacramenro LasV^ * Phoenix • Tucson • RfescottVSIl^ • Denver • eteo • Houston "^^%e->vn Home Plant Lift Station Infiltration Basin Carlsbad, Califomia October 20, 2011 Project No. 106636003 Performing a subsurface evaluation consisting of the excavating, logging, and sampling of two infiltration test excavations.

SITE AND PROJECT DESCRIPTION The existing Home Plant Lift Station is located at 2359 Carlsbad Boulevard. The site is bounded to the east by Carlsbad Boulevard and on the west by North County Transit District (NCTD) railroad tiacks. The site is relatively level with surface runoff generally to the northwest. Surface elevations range from approximately 20 feet above mean sea level (MSL) at the northwest comer to 33 feet MSL at the southeast comer ofthe site. The existing pump station, which is located near the south- east comer ofthe site, was originally constracted in 1963 and was rehabilitated in 1991. Our field reconnaissance indicates that some new fill material (on the order of 0.5 to 1.5 feet thick), has been placed along the northwest portion of the site since our 2009 geotechnical evaluation. Based on visual observations, we estimate the existing ground surface in the vicinity ofthe proposed infiltration basin to be 27 feet MSL. As shown on Figure 2, the proposed infiltration basin will be constmcted on the north portion of the site. Our review of prehminary plans by Psomas indicates that the inflltration basin will con- sist of a basin extending from the existing ground surface to an elevation of 22 feet (MSL). The area ofthe basin will be over excavated by an additional 18 inches and replaced with a blanket of select loamy sand approximately 18 inches thick. In addition, the basin sides will be sloped at a ratio of 3:1, horizontal: vertical. 106636003 L.<iQC Home Plant Lift Station Inflltration Basin October 20, 2011 Carlsbad, CaUforaia Project No. 106636003 SUBSURFACE EVALUATION Our subsurface infiltration tests were conducted on October 6, 2011, and consisted ofthe excava- tion, logging, and testing of two small-diameter soil boring excavations. The borings were advanced with a track-mounted drill rig utilizing 6-inch diameter solid stem augers. The borings were designated IT-1 and IT-2. Selected soil samples were visually classified and logged during drilling. The approximate locations of the borings/infiltration tests are shown on Figure 2. Logs of borings are attached as Figures A-l through A-2. Geologic units encountered during our subsurface exploration consisted of fill materials under- lain by old paralic deposits. As encountered, the fill material generally consisted of brown, moist, medium dense, silty sand with a few gravel and cobbles. Scattered constmction debris, including gravel and broken concrete was encountered in boring IT-2. Old paralic deposits were encoun- tered below the fill to the depth explored. In general, the material generally consisted of brown, moist, medium dense, silty sand. Review of the boring logs from our previous evaluation (Ninyo & Moore, 2009) indicated a layer of clayey sand material in boring B-1. This layer was reported at an approximate elevation of 18.5 feet MSL. If this layer is underlying the proposed infiltration basin, slower inflltration rates may be expected. A geologist should evaluate the infiltration excavation prior to the addition of the 18-inches thick sand blanket. Groundwater Groundwater not encountered in the infiltration borings. Groundwater was encountered dur- ing the excavation of our subsurface borings in 2009 at depths ranging from 23 to 31 feet bgs or at elevations of approximately -1 to +8 feet MSL. We note that variations in ground- water level may occur due to rainfall, irrigation, tidal influence and other factors. 106636003 L.doc Home Plant Lift Station Infiltration Basin Carlsbad, Califomia October 20, 2011 Project No. 106636003 INFILTRATION TESTING As a means of evaluating the infiltration characteristics of near surface materials, infiltration test- ing was performed on October 6, 2011 at the test locations. The procedure used was in general accordance with DEH guidelines (DEH, 2008). Free-draining, pea gravel was placed in the bottom of the test excavations. Lengths of 2-inch di- ameter slotted casing were installed in an upright position, and the annulus between the pipe and sidewalls was backfilled with additional gravel to mitigate the potential for caving. To begin the inflltration testing procedure, the test holes were filled with 12 inches of water. The test holes were given 30 minutes to percolate more than 5 inches of water. If 5 inches of water or more percolate within 30 minutes, then the fast test was performed. Each of the inflltration tests were eligible for the fast test which consists of taking readings every ten minutes for the next hour. Test holes were typically refilled after each reading. The infiltration test borings were backfilled at the conclusion of testing. The test results were calculated and adjusted for gravel-packed test holes. Field infiltra- tion testing data is attached, and the adjusted infiltration rates are summarized in Table 1.

AAA vc''c J'--'^-'^ '^"^ January 8, 2014 Mr. Mark Biskup City of Carlsbad 1635 Faraday Ave. Carlsbad, California 92008 Re: Archaeological Monitoring for the Home Plant Sewer Lift Station & Force Main Rehabilitation Project, City of Carlsbad, California Dear Mr. Biskup, This report presents the results of archaeological monitoring services for the Home Plant Sewer Lift Station and Force Main Rehabilitation Project (Project), located adjacent to Buena Vista Lagoon within the City of Carlsbad, California. The Project consisted of the installation of a new submersible type sewage pump station, valve vault, metering vault, backup generator, emergency storage structure, control building, 8–in. high-density polyethylene (HDPE) sewage force main, odor bed, paving, fencing, grading, drainage, landscaping, and demolition of existing facilities. The project area is shown on the San Luis Rey, California, 7.5-minute USGS topographic quadrangle, in Section 1 of Township 12S and Range 5 West (Figures 1 and 2). This investigation is provided in compliance with the California Environmental Quality Act (CEQA). The purpose of the archaeological monitoring was to identify and appropriately manage any cultural deposits that might be encountered during ground disturbance, including grading, trenching, and excavation within the project area. Monitoring of ground disturbance was conducted during the grading of portions of the Home Plant Sewer Lift Station west of Carlsbad Boulevard and the excavations of the pits for the associated facilities between the dates of July 30 and August 2, 2013. Archaeological monitoring of the trenching associated with the installation of the 8–in. HDPE sewage main along Laguna Drive was conducted on the dates of October 28, 31, and November 12, 2013. The results of the archaeological monitoring were negative, in that no prehistoric or historic cultural resources were identified during the monitoring. Archaeological Context This section provides a brief outline of the culture-historical sequence recognized in the region of the currently discussed project area. The San Dieguito period encompasses human occupation of the San Diego area prior to 7500 years before the present (B.P.). Defining characteristics of the San Dieguito artifact assemblage Mr. Biskup January 8, 2014 Page 2 include scrapers, bifacial knives, and crescent-shaped eccentrics. The artifact assemblage is thought to represent a heavy emphasis on hunting of game (Meighan 1954; Moriarty 1966; Rogers 1939, 1945; True 1958, 1966, 1970; Warren, 1966, 1967, 1987; Warren and True 1961; Warren et al. 1961). The La Jolla period, followed by a hiatus/transition, encompasses a time frame between approximately 7500 B.P. and 1300 B.P. The La Jolla period is thought to represent an emphasis on littoral resources, as indicated by dense shell midden sites. The tool assemblage is defined by simple stone cobble tools and an increased emphasis on ground stone implements (Gallegos 1985, 1987, 1992; Meighan 1954; Moriarty 1966; Rogers 1939, 1945; True 1958, 1966, 1970; Warren 1967, 1966, 1987; Warren and True 1961; Warren et al. 1961). The Late Prehistoric period, extending from the end of the La Jolla period to the beginning of the historic period, is typically assigned a range of dates from 1300 or 800 B.P. to 200 B.P. This period is often broken down into various subdivisions; Yuman I-III for the central and southern San Diego County coast (Rogers 1939, 1945); San Luis Rey-Luiseño periods for the northern coast and interior, and the Cuyamaca-Diegueño periods for the central and southern interior, (Meighan 1954; True 1958, 1966, 1970). The Late Prehistoric period is thought to include the introduction of the bow and arrow, use of pottery, and a possible emphasis on inland plant resources (Meighan 1954; Rogers 1945; True 1958, 1966, 1970; True and Waugh 1982; Warren 1964, 1968). The historic period in coastal San Diego County was formally initiated in A.D. 1542, with the arrival of the maritime expedition of Juan Rodríguez Cabrillo. However, substantial impacts may only have begun in 1769, with the overland party under Gaspar de Portolá and Junípero Serra. Important influences reaching the study area began with the establishment of a mission and a presidio in San Diego and with frequent overland treks north from San Diego along the coastal plain. Additional missions were established at San Juan Capistrano (1776) and San Luis Rey (1798). After Mexico won its independence from Spain in 1821, the issuance of private land grants began, including Agua Hedionda Rancho, created in 1842. Annexation of California to the United States in 1848 and the gold rush in northern California the following year greatly increased the rate of settlement and of social and cultural change in the region. Cycles of boom and bust ensued during the late nineteenth century, while growth was more persistent through the twentieth century. The city of Carlsbad was incorporated in 1952. The Monitoring Effort, Observations, and Results The archaeological monitors for this project were Michael DeGiovine and Beniamino Volta. James T. Daniels, Jr., ASM Senior Archaeologist, managed the monitoring effort for ASM. The ASM monitors oversaw surface removal, grading, excavation, and backhoe trenching operations associated with the project. During the surface grading and deep pit excavations for the Lift Station facilities between the dates of July 30 and August 2, 2013, the top 4 to 5 ft. of dirt was determined to be fill material brought in for the construction of the previous facility. From approximately 4 to 6 ft. below the ground surface, the sediment consisted of intermittent strata of oxidized sand and grey fine sand (Figure 3). The fill contained associated fragments of trash and debris, including cement/concrete chunks, brick fragments, and other modern trash. No archaeological material was encountered. Mr. Biskup January 8, 2014 Page 3 Archaeological monitoring for the trenching for the 8–in. HDPE sewage main along Laguna Drive was conducted on the dates of October 28, 31, and November 12, 2013. The trench was an average of 5 ft. wide by 12 ft. deep, although the excavations reach a maximum depth of 13.5 ft. deep at some points. No cultural materials were observed in the profile of the trench or during excavation. The soil matrix consisted of light brown loamy sand. No changes in stratigraphy were observed; profiles were uniform from below the asphalt down to maximum depth (Figure 4 and 5). At the west end of the trench, the soil appeared to be fill from previous construction work for the installation of pipes. Around the intersection of Laguna Drive and Buena Vista, a compact loamy sand was noted as possibly native soil; however the soil matrix was observed to be completely sterile with respect to cultural materials. Conclusions and Recommendations ASM did not identify any cultural deposits during the grading, trenching, and excavation associated with the construction of the Home Plant Sewer Lift Station and Force Main Rehabilitation. No additional archaeological work is recommended for this project. Sincerely, James T. Daniels, Jr., M.A., RPA Senior Archaeologist ASM Affiliates Attachments: Figure 1. General vicinity map.
